Spacco is a pretty popular spot in the summer thanks to its off-the-beaten-path patio!
Even though the patio fills up on the regular, there seems to always be ashortage of waitstaff, meaning you'd better order for the rest of the night when you get your chance! To make a point I have had the pleasure of waiting a full hour for a mixed drink, as well as having the waitress forget completely what I had ordered.
The food is just ok, and the pizza is probably the best bet, though I found the spaccato a bit too salty (sausage, sun-dried tomato etc).
Spacco also has several pool tables, which are available for an unreasonable $20/hr! That being said, you know you can find an empty table here at almost any time!
In brief, give it a go if you are looking for a place that can accommodate a large group and have forgotten to plan ahead!
